Nanotechnology and acne - Research Paper Example Nanotech medication can be devised that have strong antimicrobial properties to treat this infectious skin disease. The use of encapsulated benzoyl oxide in chitosan-alginate nanoparticles is used for the purposes of improving the activity as well as the tolerability of the anti-acne agent. Biodegradable and biocompatible nanoparticles are used in the synthesis of nontoxic anti-acne agents 6Ï€(d1 - d2)gr2/ÃŽ ·.These drugs will use stokes law once they have dissolved in the body fluid to diffuse to the target site of action. As the nanoparticles will be sinking into the body fluid forces will be acting on it. The force that will be acting in resistance of the particle will be equivalent to 6Ï€rÃŽ ·v, where r represents the radius of the blood vessel, ÃŽ · is the body fluid viscosity, and v represents the velocity at which the nanotech drug will be moving along the blood vessels. The force acting downward is equal to Ï€r2 (d1 - d2)g, where d1 represent the density of the body, d2 is the density of the blood, and g represents gravitational force. Upward and downward forces are always in balance at any constant velocity of fall. Stokes law finds its application in several fields hence its validity in the use of nanotech drugs in the treatment of acne is authentic. Therefore, when the formula is combined together, the velocity at which the nanotech drugs will be t=moving at will be v = 6Ï€(d1 - d2)gr2/ÃŽ · (Farokhzad & Langer, 2009) useful in the treatment.

Unit 4 Discussion Board - Essay Example Creating the sort of association with the followers probably derive all other associated activities with leadership. In this regard, it therefore not matter whether we need a new generation of leadership as well as new gender. As long as leadership can and should associate itself with the followers, there arises hardly a need to argue for a shift in the ways leadership is pursued and practiced. Though it has been argued that leadership has been viewed and studied with respect to the masculinity (-Metcalfe, 2002) however this is not the fact in its entirety. It must be noted that almost all the leadership whether in the corporate world or in political world was masculine and it was probably because of this reason that the leadership has mostly being studied within that context. In order to be an effective leader, there are various personal traits and qualities which a leader must have in order to be effective. These include from motivating the employees to making decisions of strategic nature. However, these traits are not gender specific in nature however there are certain attributes specific to both male and female leaders which both make them effective in their fields and leadership is largely gender neutral. (Gedney, 1999). However historically the evolution of leadership theories started with the focus on the masculine characteristics of the leaders. The so called Great Man theories of 1930s and 1940s greatly emphasized on the personal characteristics of the leaders including their intelligence, personal charisma etc. The great man theories largely emphasized on the role of males into the leadership however that was an era where there were very few opportunities left for the women to participate into the mainstream economy. Lack of opportunity was the refore the main reason behind the development of theoretical framework which were largely focusing on the masculine characteristics o f the leaders. This has historical connotations also because the
